Spohn Performance 985-987 Features:

Don't use your old rusty mounting bolts when installing front lower and upper control a-arms on your 1993-2002 GM F-Body Camaro and Firebird (if you managed to get the nuts off without breaking the bolts!).On the lower a-arms the external star locking washer is placed underneath the bolt head to lock in the front end alignment settings at the k-member a-arm mounting slots. These make a big difference on powder coated tubular k-members compared to re-using the factory hardware.Our front lower control a-arm mounting hardware kit includes:(4) 14 mm Grade 10.9 bolts(4) 14 mm flanged head steel lock nuts(4) 14 mm external star locking washersOur front upper control a-arm mounting hardware kit includes:(4) 12 mm Grade 10.9 bolts (zinc plated)(4) 12 mm flanged head steel lock nuts (zinc plated)(4) 12 mm Grade 8 flat washers (zinc plated)
